Semiconductor light emitting device
First Claim
1. A semiconductor light emitting device comprising:
- a semiconductor light emitting portion having a first contact layer of a first conductivity, a second contact layer of a second conductivity and an active layer sandwiched between the first and second contact layers;
a transparent electrode which substantially entirely covers a surface of the second contact layer in ohmic contact with the surface of the second contact layer and is transparent to a wavelength of light emitted from the semiconductor light emitting portion; and
a metal reflection film which is opposed to substantially the entire surface of the transparent electrode and electrically connected to the transparent electrode, and reflects the light emitted from the semiconductor light emitting portion and passing through the transparent electrode toward the semiconductor light emitting portion;
further comprising a transparent insulation film disposed between the transparent electrode and the metal reflection film, whereinthe metal reflection film is connected to the transparent electrode via an opening formed in the transparent insulation film; and
wherein the reflection film is provided on a surface portion of the transparent insulation film opposite from the semiconductor light emitting portion and substantially entirely covers a region of the transparent insulation film opposed to the semiconductor light emitting portion.
